CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of and claims priority to U.S. patent application Ser. No. 12/783,064, filed on May 19, 2010, which is herein incorporated by reference in its entirety and which claims priority to U.S. Provisional Application No. 61/179,707, filed May 19, 2009, which is herein incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates generally to wireless communications service and, more particularly, to systems, methods, and mobile devices for providing a user interface to facilitate access to prepaid wireless account information.

BACKGROUND

Wireless telecommunications services are provided to customers via one of two payment methods—prepaid and postpaid. Postpaid accounts are designed such that if the customer exceeds the number of voice minutes, data capacity, text messages, or other services allocated to their account in a billing cycle, the postpaid customer will be charged for the excess services at the end of the billing cycle. Often times, the customer is unaware of the overage and is requested to pay an unexpected amount at the end of the billing cycle.

Services, such as AT&T's Rollover® service, aim to eliminate overages by accumulating unused minutes at the end of each billing cycle for use in future billing cycles. For example, if a customer uses 900 minutes of a 1000 minute service plan during a billing cycle, the remaining 100 unused minutes are added to the customer's total available Rollover® minutes. If the customer exceeds their 1000 minute service plan during a future billing cycle, the customer's Rollover® account is debited the overage amount of minutes instead of the customer being charged overage fees for the excess minutes. Minutes in a customers Rollover® account are typically set to expire after a predetermined time, such as every year.

Prepaid customers typically purchase a credit for a predetermined number of voice minutes prior to receiving wireless voice service. By purchasing credit in advance of use on a wireless service network, a customer can access a wireless service network without contractual obligation and an ongoing bill (e.g., re-occurring bill). A customer may then use the wireless network until the expiration of the purchased, or prepaid, credit.

SUMMARY

According to one aspect of the present disclosure, a method for operating a mobile device includes, in response to receiving a swipe gesture via a user interface of the mobile device, displaying a balance of a prepaid wireless service account on a display of the mobile device.

In one embodiment, the balance is a currency amount such as a monetary currency (e.g., U.S. dollars). In another embodiment, the currency amount is in a proprietary currency such as a number of minutes.

In one embodiment, the user interface is a capacitive touch sensor. In another embodiment, the user interface is a touchscreen interface.

In one embodiment, the method further includes, in response to receiving a second swipe gesture via the user interface, displaying an expiration time to identify a time remaining until the balance expires.

In one embodiment, the method further includes displaying an expiration time to identify a time remaining until the balance expires upon receiving the swipe gesture during a threshold time period. The threshold time period may be a custom time period set at the mobile device. Alternatively, the threshold time period may be a custom time period set in response to a request received from a server.

In one embodiment, the method further includes, in response to receiving a second swipe gesture via the user interface in a direction opposite the swipe gesture, removing the displayed currency amount from the display.

In one embodiment, the method further includes, in response to a call being initiated at the mobile device, removing the displayed currency amount from the display.

In one embodiment, the method further includes, prior to displaying the balance, generating a balance request to request the balance for the prepaid wireless service account from a prepaid billing system in response to receiving the swipe gesture, transmitting the balance request to the prepaid billing system, and receiving the balance in response to the balance request. The balance request may be an unstructured supplementary service data (USSD) code to request the balance for the prepaid wireless service account. The balance request may be transmitted to the prepaid billing system by way of a USSD gateway. The balance may be received from the USSD gateway in a USSD response. Alternatively, the balance may be received as a text message. The balance may be accompanied by an expiration date of the balance. The USSD code may be *777# or another USSD code.

According to another aspect of the present disclosure, a tangible computer-readable medium includes computer-executable instructions that, when executed by a processor of a mobile device, cause the processor to perform steps of the aforementioned method.

According to yet another aspect of the present disclosure, a mobile device includes a display, a user interface in communication with the display, a processor in communication with the user interface, and a memory in communication with the processor. The memory is configured to store instructions that, when executed by the processor, cause the processor to perform steps of the aforementioned method.

DETAILED DESCRIPTION

As required, detailed embodiments of the present disclosure are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary examples of the disclosure that may be embodied in various and alternative forms, and combinations thereof. As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as an illustration, specimen, model or pattern. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials or methods have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

Turning first to FIGS. 1A-1C, a mobile device 100 is illustrated according to one embodiment of the present disclosure. The illustrated mobile device 100 is a “candybar”-style phone. Alternatively, the mobile device 100 may be a slide-style phone or a flip-style phone. The mobile device 100 and the components (e.g., display, keypad, and other interface components) thereof may be configured in other styles. As illustrated, the mobile device 100 includes a display 102, a capacitive touch sensor 104, and a keypad 106.

The display 102 may be any display types, including, but not limited to, a liquid crystal display (LCD), a plasma display, an organic light emitting diode (OLED) display, an LED display, an LED-backlit LCD, a touchscreen display, a multi-touch touchscreen display, a rear projection display, a 3-D display, a laser display, a holographic display, any combinations thereof, and the like. The display 102 may be used to display information relative to the operation of the mobile device 100 including, for example, displaying calling information, device status (e.g., battery level, date, time), network operator, message waiting indicator, navigation menus, application launch, and the like.

The capacitive touch sensor 104 is designed under principles of capacitive sensing technology. The illustrated capacitive touch sensor 104 is designed to overlay a portion of the mobile device 100 as a standalone button as illustrated. Alternatively, the capacitive touch sensor 104 may be integrated into a portion or the entirety of the display 102, thereby providing a touchscreen interface for a portion or the entire display 102. The capacitive touch sensor 104 may be implemented so as to give a perception of a touchscreen interface even though the touch portion is a standalone touch-sensitive button that is separate from the display 102. Moreover, the capacitive touch sensor 104 may be sized and shaped as illustrated or sized and shaped in a variety of other ways.

In one embodiment, the capacitive touch sensor 104 senses a finger or object (e.g., a stylus or other object) moving from left-to-right or right-to-left in a swiping motion, referred to herein as a “swipe gesture.” The capacitive touch sensor 104 detects the swipe gesture and initiates a prepaid application stored in a memory (illustrated in FIG. 2 and described herein below) of the mobile device 100. In some embodiments, the prepaid application is configured to retrieve data for a prepaid wireless service account associated with the mobile device. In some embodiments, the data includes a remaining balance and/or an expiration date.

As illustrated in FIG. 1B, a first swipe gesture triggers the prepaid application to display a remaining balance 108. The remaining balance may be displayed in any currency, including government issued currency and proprietary currency offered by a particular company (e.g., credits or minutes provided by a wireless service provider). As illustrated in FIG. 1C, a second swipe gesture triggers the prepaid application to display an expiration date 110. Alternatively, the first swipe gesture and second swipe may cause display of the expiration date and the remaining balance, respectively. In some embodiments, the first swipe gesture triggers both the remaining balance and the expiration date to be displayed. In some embodiments, a swipe gesture in a direction opposite the first or second swipe gesture removes some or all previously displayed information. Moreover, in some embodiments, the displayed information is removed in response to an outgoing call being initiated or an incoming call arriving or being answered, for example, or during other device operations.

Turning now to FIG. 2, a schematic block diagram of an exemplary device 100 for use in accordance with embodiments of the present disclosure is illustrated. Although not all connections are shown between the components illustrated in FIG. 2, the components can interact with each other to carry out device functions.

In some embodiments, the wireless network 302 includes network elements to facilitate the exchange of USSD messages to/from the mobile device 100 and a USSD gateway 306, such as described below with reference to FIGS. 4-6. The USSD gateway 306, in turn, may communicate with one or more USSD applications 308 to retrieve prepaid account data from a prepaid billing system 310 and/or a prepaid accounts database 312 via the various methods described herein. In other embodiments, the prepaid application 212 communicates with a proxy server 314 via the mobile device 100 through the network 302 in accordance with the method described below with reference to FIG. 7 to retrieve prepaid account data. The illustrated proxy server 314 is in communication with the billing system 310 and the prepaid accounts database 312.

Turning now to FIG. 4, a method 400 is illustrated, according to one exemplary embodiment of the present disclosure. It should be understood that the steps of the method 400 are not necessarily presented in any particular order and that performance of some or all the steps in an alternative order(s) is possible and is contemplated. The steps have been presented in the demonstrated order for ease of description and illustration. Steps can be added, omitted and/or performed simultaneously without departing from the scope of the appended claims. It should also be understood that the illustrated method 400 can be ended at any time. Some or all steps of this process, and/or substantially equivalent steps, can be performed at least partially by execution of computer-readable instructions included on a computer-readable medium, such as the memory 204.

The method 400 begins and flow is to block 402, wherein the prepaid application 212 is initiated on the mobile device 100 in response to a launch mechanism being enabled. In the illustrated embodiment of FIG. 1, the launch mechanism is a swipe gesture received by the mobile device 100 through the capacitive touch sensor 104. Alternatively, another button, gesture, motion, or other input is used as the launch mechanism for the prepaid application 212. At block 404, the prepaid application 212 sends a USSD code to the USSD gateway 306 to request prepaid account data including, for example, “remaining balance” and/or “expiration date” data. In one embodiment, the prepaid application 212 emulates dialing *777# to request a “balance remaining” and/or “expiration date” for a prepaid account associated with the mobile device 100. Other USSD codes are contemplated.

At block 406, the prepaid application 212 receives a USSD response message from the USSD gateway 306. The USSD response message may be a typical USSD response message for a *777# code, including data fields for the “balance remaining” and “expiration date” for the requested prepaid account. Alternatively, the USSD response message includes data fields for the “balance remaining” or the “expiration data.” At block 408, the prepaid application 212 parses the USSD response message to extract the values in these data fields. At block 410, the prepaid application 212 displays the “remaining balance” and/or the “expiration date” according to the data received and/or how the prepaid application 212 is configured to display the received data. In one embodiment, the prepaid application 212 is configured to display the “remaining balance” and/or the “expiration date” in response to a first and a second swipe gesture, respectively, or vice versa. In another embodiment, both data types are displayed following a single swipe gesture. In any case, the displayed data may be removed following a subsequent swipe or other gesture. As described above, other gestures or inputs are contemplated. The method 400 can end.

Turning now to FIG. 5, an exemplary method 500 is illustrated, according to another embodiment of the present disclosure. It should be understood that the steps of the method 500 are not necessarily presented in any particular order and that performance of some or all the steps in an alternative order(s) is possible and is contemplated. The steps have been presented in the demonstrated order for ease of description and illustration. Steps can be added, omitted and/or performed simultaneously without departing from the scope of the appended claims. It should also be understood that the illustrated method 500 can be ended at any time. Some or all steps of this process, and/or substantially equivalent steps, can be performed at least partially by execution of computer-readable instructions included on a computer-readable medium, such as the memory 204.

The method 500 begins and flow is to block 502, wherein a communication is terminated. For example, a call is terminated during which a portion of a remaining balance for a prepaid account is exhausted, thereby prompting the prepaid billing system 310 or some combination of the prepaid billing system 310 and a USSD application (e.g., the illustrated USSD application 308) to generate a USSD message including data fields for “remaining balance” and/or “expiration date” updated to reflect the new remaining balance and/or new expiration date (e.g., call began before midnight and terminated after midnight thereby decreasing the number of days to expire by one day). The prepaid billing system 310 sends the USSD message to the mobile device 100.

At block 504, the mobile device 100 receives the USSD message. At block 506, the mobile device 100 caches the values for the “remaining balance” and/or “expiration date” data fields in the memory 204. At block 508, the prepaid application 212 is initiated on the mobile device 100 in response to a launch mechanism being enabled. In the illustrated embodiment of FIG. 1, the launch mechanism is a swipe gesture received by the mobile device 100 through the capacitive touch sensor 104. Alternatively, another button, gesture, motion, or other input can be used as the launch mechanism for the prepaid application 212. At block 510, the prepaid application 212 retrieves the values from the memory 204.

At block 512, the prepaid application 212 displays the “remaining balance” and/or the “expiration date” according to the values retrieved and/or how the prepaid application 212 is configured to display the received data. In one embodiment, the prepaid application 212 is configured to display the “remaining balance” and/or the “expiration date” in response to a first and a second swipe gesture, respectively, or vice versa. In another embodiment, both data types are displayed following a single swipe gesture. In any case, the displayed data may be removed following a subsequent swipe or other gesture. As described above, other gestures or inputs are contemplated. The method 500 can end.

Turning now to FIG. 6, a method 600 is illustrated, according to another embodiment of the present disclosure. It should be understood that the steps of the method 600 are not necessarily presented in any particular order and that performance of some or all the steps in an alternative order(s) is possible and is contemplated. The steps have been presented in the demonstrated order for ease of description and illustration. Steps can be added, omitted and/or performed simultaneously without departing from the scope of the appended claims. It should also be understood that the illustrated method 600 can be ended at any time. Some or all steps of this process, and/or substantially equivalent steps, can be performed at least partially by execution of computer-readable instructions included on a computer-readable medium, such as the memory 204.

The method 600 begins and flow is to block 602, wherein the prepaid billing system 310 processes a transaction to update a prepaid wireless service account associated with the mobile device 100. The transaction may be conducted in a variety of ways, all of which result in a change being made to the balance, the number of minutes, and/or the expiration date for all or a portion of the number of minutes or balance on the prepaid account. For example, the transaction may be an Internet transaction, a retail transaction, a kiosk transaction, a telephone transaction, an SMS transaction, an MIMS transaction, a USSD transaction, or another electronic transaction. At block 604, the prepaid billing system 310 instructs a USSD application 308 to send a USSD message including data fields for a new “remaining balance” and/or a new “expiration date” to the mobile device 100.

At block 606, the mobile device 100 receives the USSD message. At block 608, the mobile device 100 caches the values for the “remaining balance” and “expiration date” data fields in the memory 204. At block 610, the prepaid application 212 is initiated on the mobile device 100 in response to a launch mechanism being enabled. In the illustrated embodiment of FIG. 1, the launch mechanism is a swipe gesture received by the mobile device 100 through the capacitive touch sensor 104. Alternatively, another button, gesture, motion, or other input can be used as the launch mechanism for the prepaid application 212. At block 612, the prepaid application 212 retrieves the values from the memory 204.

At block 614, the prepaid application 212 displays the “remaining balance” and/or the “expiration date” according to the values received and/or how the prepaid application 212 is configured to display the received data. In one embodiment, the prepaid application 212 is configured to display the “remaining balance” and/or the “expiration date” in response to a first and a second swipe gesture, respectively, or vice versa. In another embodiment, both data types are displayed following a single swipe gesture. In any case, the displayed data may be removed following a subsequent swipe or other gesture. As described above, other gestures or inputs are contemplated. The method 600 can end.

Turning now to FIG. 7, a method 700 for operating the mobile device 100 is illustrated, according to another embodiment of the present disclosure. It should be understood that the steps of the method 700 are not necessarily presented in any particular order and that performance of some or all the steps in an alternative order(s) is possible and is contemplated. The steps have been presented in the demonstrated order for ease of description and illustration. Steps can be added, omitted and/or performed simultaneously without departing from the scope of the appended claims. It should also be understood that the illustrated method 700 can be ended at any time. Some or all steps of this process, and/or substantially equivalent steps, can be performed at least partially by execution of computer-readable instructions included on a computer-readable medium, such as the memory 204.

The method 700 begins and flow is to block 702, wherein the prepaid application 212 is initiated on the mobile device 100 in response to a launch mechanism being enabled. In the illustrated embodiment of FIG. 1, the launch mechanism is a swipe gesture received by the mobile device 100 through the capacitive touch sensor 104. Alternatively, another button, gesture, motion, or other input can be used as the launch mechanism for the prepaid application 212.

At block 704, the prepaid application 212 sends a request to the proxy server 314 requesting the current “remaining balance” and/or “expiration date” for a prepaid account associated with the mobile device 100. The proxy server 314 communicates with the prepaid billing system 310 to retrieve the requested information and reports back to the mobile device 100.

At block 706, the prepaid application 212 receives a response message from the proxy server 314 including the requested values. At block 708, the prepaid application 212 parses the response message to extract the values of the “remaining balance” and the “expiration date” data fields. At block 710, the prepaid application 212 displays the “remaining balance” and/or the “expiration date” according to the values extracted and/or how the prepaid application 212 is configured to display the received data. In one embodiment, the prepaid application 212 is configured to display the “remaining balance” and/or the “expiration date” on a first and a second swipe gesture, respectively, or vice versa. In another embodiment, both data types are displayed following a single swipe gesture. In any case, the displayed data may be removed following a subsequent swipe or other gesture. As described above, other gestures or inputs are contemplated. The method 700 can end.

While the present disclosure has been described with reference to prepaid wireless service accounts predominately, it is contemplated that systems, devices, and methods described herein can additionally or alternatively be applied to postpaid wireless service accounts. For postpaid accounts, an application stored on the mobile device 100 may use other USSD codes, such as *225# and *646# to retrieve an account bill balance and/or time (e.g., minutes) balance, respectively, for presentation on the display 102 of the mobile device 100 in response to receiving input from a launch mechanism, as described above.

The disclosed embodiments are merely examples that may be embodied in various and alternative forms, and combinations thereof. As used herein, for example, “exemplary,” and similar terms, refer expansively to embodiments that serve as an illustration, specimen, model or pattern.
